One is a very good magnesium drink. The other is a magnesium drink plus everything else your night needs. The question is how much you want one product to do.
If you’re comparing Moongreens vs Magnesi-Om, you’re really comparing two different scopes. Moon Juice’s Magnesi-Om is a beautifully made magnesium-and-L-theanine drink for calm, focus and regularity. Moongreens includes magnesium too — but it’s one layer of a larger night recovery formula. Neither is wrong; they’re built for different jobs.
Both are melatonin-free, both taste of berries, and both are well-tested. So the decision comes down to two things: the form of magnesium each uses, and how much of your night you want a single scoop to handle.
The form of magnesium matters
Magnesi-Om uses a chelate blend of three magnesiums — gluconate, acetyl taurinate and citrate — and citrate is the dominant one. Citrate is genuinely useful, and Moon Juice is upfront that one of its benefits is regularity, because citrate draws water into the gut. The flip side of that same property is that it can loosen things more than some people want from a nightly drink.
Moongreens uses Magnesium Bisglycinate Chelate (Albion®) — a form chosen specifically because it’s gentle on the gut and well absorbed, without the laxative tendency. If you’ve ever found a magnesium drink sent you the wrong direction overnight, the form is usually why.

One mineral, or the whole night
Magnesi-Om does one thing and does it well: magnesium and L-theanine for calm. If that’s all you’re after, it’s a clean, elegant choice. But magnesium is one piece of a good night, not the whole of it.
Moongreens treats the night as a system. Magnesium bisglycinate sits alongside KSM-66® Ashwagandha and L-Theanine for the cortisol of a wired mind, L-Glycine and 5-HTP from Griffonia Seed for sleep depth and your own melatonin pathway, and a greens and gut layer with ProbioSEB® CSC-3 and BioPerine®. If you bought Magnesi-Om hoping it would fix your sleep, the honest answer is that magnesium alone usually only takes you part of the way.
So which one should you choose?
If you specifically want a magnesium top-up for daytime calm and regularity, and you’re not asking it to be a full sleep solution, Magnesi-Om is a lovely, well-sourced product.
If you want magnesium in a gentler form and as part of a complete night recovery formula — cortisol, sleep depth, gut and greens together — that’s Moongreens. If form is what you care about most, the magnesium question comes up again in Moongreens vs Magnesium; for the all-in-one argument, see Moongreens vs MoonBrew.

Try it for a full sleep cycle
Thirty nights isn’t long enough to judge a recovery formula — the adaptogens take six to eight weeks to reach full effect. So Moongreens comes with a 90-night guarantee: enough time to feel the difference in how you wake up, not just how you fall asleep. If it isn’t doing its job, you haven’t lost anything.
